Abstract
A temperature estimation method includes bringing a first thermal resistance member into contact with the test subject, measuring a first temperature of a surface of the test subject, calculating a temperature normalized by an instantaneous value of the first temperature of the surface of the test subject and the temperature of the first thermal resistance member and a setting value of the temperature of the surface of the test subject, deriving, as a temperature wave arrival time, deriving a proportionality coefficient based on the temperature wave arrival time, measuring a second temperature of the surface of the test subject, measuring a third temperature of a surface of the second thermal resistance member on a side opposite to the surface on the test subject side, and calculating an internal temperature of the test subject based on the second temperature, the third temperature, and the proportionality coefficient.
